After LASIK, a small number of patients may still need glasses due to residual prescription, regression over time, or age-related changes like presbyopia. Understanding why helps set realistic expectations.
Key Facts
- Residual prescription: LASIK under-corrected slightly (more common with high prescriptions)
- Regression: Vision drifts back over years (touch-up surgery available)
- Presbyopia: Age-related near vision loss (40+ years), unrelated to LASIK
- Dry eye: Temporary blurriness from dry eye can mimic need for glasses
- Incomplete healing: Vision still adjusting in first 3 months
Guidelines & Tips
- If glasses are still needed at 1 month — do not panic, vision may still be improving
- Wait until 3 months post-LASIK for a final accurate refraction test
- Discuss enhancement (touch-up LASIK) with your surgeon at the 3-month check
- Presbyopia-correcting options (monovision LASIK, reading glasses) are available if needed
- Long-term regression is rare with modern LASIK technology
- Annual eye check-ups help detect and address any prescription changes early
